Brief Functional Description
The low cost basic FlexRay transceiver is part of the
electrical, physical layer in a FlexRay communication
network. The E
910.54
provides an interface between
the twisted pair physical bus medium and a commu-
nication controller (CC). An SPI interface connects the
bus driver (BD) to a host controller (HOST) to provide
status information concerning failure detection on the
bus lines (e.g. short-circuits, ground loss) and overtem-
perature condition. An interrupt signal is generated
whenever the failure status changes.
